dc.description.abstractFire blight disease caused by pathogenic bacterium Erwinia amylovora, is the serious disease of pear, and there is not a certain chemical management against this disease except antibiotic-type compounds such as streptomycin. It is very important to improve new fire blight resistant cultivars in case of integrated disease management. With this purpose, different crosses have been made between Pyrus communis varieties that have good fruit characteristics and resistant cultigens. Besides, self and open pollination treatments have been carried out in maternal plants. The disease resistance level of the hybrids obtained from these combinations was determined by artificial inoculations by Erwinia amylovora in greenhouse conditions. A total of 3284 hybrids were inoculated, and 2631 of them survived and were distributed to different susceptibility classes. 19.88% of the inoculated hybrids was killed by Erwinia amylovora. Total distribution of the hybrids to susceptibility classes was as 6.18% in class "A- slightly susceptible", 3.11% in class "B- less susceptible", 8.89% in class "C- mid-susceptible", 20.28% in class "D- susceptible; and 61.54% in class "E- very susceptible". Majority of class "A- slightly susceptible" hybrids were obtained from 'Magness' x 'Ankara' combination. 'Kieffer' a 'Santa Maria', 'Kieffer' open pollination, 'Magness' x Aka; 'Magness' a 'Kieffer', 'Magness' x 'Santa Maria', 'Mustafa Bey' x 'Moonglow' treatments displayed good results with respect to 'A- slightly susceptible" character. It is very important to evaluate these hybrid pear populations through different fruit and tree characteristics in the future.en_US
